System Overview

Typical Federal Office Building Potable Water Use
Typical Federal Office Building Potable Water Use

A typical Federal office building with 200 employees uses about 3,000 gallons of water in one day. The daily water usage breaks down under these categories.

The Federal Government spends an estimated $1 billion on water and sewer services annually.1 This includes 148 to 165 billion gallons of potable water, enough to supply a state the size of New Jersey, or 8 million people.2 Of this amount, a significant percentage can be preserved through water conservation measures3 targeting:

  • Distribution system improvements (including leak detection, repair, and replacement)
  • Heating and cooling (including steam boilers, cooling towers, and single pass cooling)
  • Landscaping/Irrigation
  • Laboratory and medical equipment (including water purification, sterilization equipment, and washing applications)
  • Distribution system improvements (including leak detection, repair, and replacement)

Sustainable water systems in commercial office buildings are considered a high priority due to

  • New and existing water resources becoming increasingly scarce or too costly to harvest
  • Spiking water and sewer utility rates (100-400%)1 during the last decade

Moderate efficiency efforts and proper maintenance of water system components can save the Federal Government approximately forty percent of its water and related energy use, leading to beneficial resource, human, and financial implications.
